Which word indicates the main or foremost position?

The word "primary" indicates the main or foremost position. In various contexts, "primary" refers to something that is first in importance, order, or rank. It denotes the top or leading position in a hierarchy or list, suggesting that whatever is described as primary holds significant value or priority over other elements.

For example, in educational settings, primary education refers to the first stage of formal education, highlighting its foundational role in a child's learning process. Similarly, in discussions about responsibilities or goals, something designated as primary is usually the most critical task that needs to be addressed first.

The other words, while they may have specific implications in different contexts, do not convey the same sense of importance or precedence as "primary." "Secondary" refers to a second level or position, "tertiary" relates to a third level, and "auxiliary" suggests something that serves as a support or additional role. Thus, they do not capture the meaning of being in the foremost position like "primary" does.
